To establish the relationship between the static viscoelastic and the tribological properties,creep and friction experimentswere performed on PP-EPDM,PP-GF30 and ABS through a UMT-Ⅱ multi-functional micro-friction test machine.Results showed thatPP-EPDM has the smallest creep rate and the better dimensional stability.This was related to the more complicated internal net structure,and the local slip and diffusion were more difficult than PP-GF30 and ABS under load.The Simulation Study of Burgers model foundedthat the viscosity coefficients of PP-EPDM was the smallest and the stiffness coefficient was the biggest,which exhibited a more apparentviscosity performance.The friction coefficient and wear depth of PP-EPDM were smaller than those of PP-GF30 and ABS,therefore,it has better wear resistance.Higher viscosity performance is favourable for friction coefficient improvement,and this goes againstimproving the wear resistance.Under the same conditions,PP-EPDM will be a better choice.
